I'm sure most of you are familiar with APOD (Astronomy Picture of the Day), and it's probably been posted before, but here it is again for those that haven't seen it!

Yep, me too! Just go to the link in my first post, then scroll down to archives and click on that. They have pictures going back to 1995 at least! Awesome!

Hay Dan....go to 2007 May 28 ..the hole in Mars.....What the heck is that?
And post it...because I cannot...argh

A Hole in Mars
Credit: NASA, JPL, U. Arizona Explanation: Black spots have been discovered on Mars that are so dark that nothing inside can be seen. Quite possibly, the spots are entrances to deep underground caves capable of protecting Martian life, were it to exist. The unusual hole pictured above was found on the slopes of the giant Martian volcano Arsia Mons. The above image was captured three weeks ago by the HiRISE instrument onboard the Mars Reconnaissance Orbiter currently circling Mars. The holes were originally identified on lower resolution images from the Mars Odyssey spacecraft, The above hole is about the size of a football field and is so deep that it is completely unilluminated by the Sun. Such holes and underground caves might be prime targets for future spacecraft, robots, and even the next generation of human interplanetary explorers.

That is so strange looking to me And it must be HUGE!

A Hole in Mars Close Up

Now how do they know that's a volcano? Wouldn't it have a mountainous peak? it looks flat to the surface.

[Dantheman62]

It's not a volcano, it's just near volcanos.

[BROOK]

Oh...

[Dantheman62]

I like the last picture where you can actually see an inside wall going down!

[BROOK]

Yeah..me too. Wonder what is down there

Stickney Crater
Credit: HiRISE, MRO, LPL (U. Arizona), NASA Explanation: Stickney Crater, the largest crater on the martian moon Phobos, is named for Chloe Angeline Stickney Hall, mathematician and wife of astronomer Asaph Hall. Asaph Hall discovered both the Red Planet's moons in 1877. Over 9 kilometers across, Stickney is nearly half the diameter of Phobos itself, so large that the impact that blasted out the crater likely came close to shattering the tiny moon. This stunning, enhanced-color image of Stickney and surroundings was recorded by the HiRISE camera onboard the Mars Reconnaissance Orbiter as it passed within some six thousand kilometers of Phobos in March of 2008. Even though the surface gravity of asteroid-like Phobos is less than 1/1000th Earth's gravity, streaks suggest loose material has slid down inside the crater walls over time. Light bluish regions near the crater's rim could indicate a relatively freshly exposed surface. The origin of the curious grooves along the surface is mysterious but may be related to the crater-forming impact.

Space Station in the Moon
Credit & Copyright: Eric J. Zbinden Explanation: On February 2nd, a first quarter Moon shone in planet Earth's early evening sky. As seen from a location on the US west coast near Mt. Hamilton, California, the International Space Station also arched above the horizon, crossing in front of the Moon's sunlit surface. The space station's transit lasted 0.49 seconds.
